[ZPT] determining the value of a folder's property

[Tamir Halperin]

thx, Robert.

Would the sorting of the folders also be possible using dtml? Imagine =
another property, in addition to "navigation". Let's call it "navsort". =
Is it possible to use dtml somehow to retrieve the folders based on the =
value of the navsort proerty?
